Short story is the thread on the head is stripped, what are my options...?

all help is appreciated.

(06 GSXR 600)

I have some 750 cams that will be an upgrade to the 600 cams- you have to get adjustable cam gears fitted. It's the same upgrade as getting the Yoshimura "Stage 1" cams.

Sam's Cycles have a head for that engine- it will likely be cheaper to just replace the head with a good used one instead of getting it repaired. A helicoil just won't do the job for a spark plug in an aluminum head.

It should be able to be fixed while still on the engine, and a helocoil properely installed will actually be better than stock, I have some very high end cylinder heads and they helicoil all sparkplug holes when they are brand new, they also have better repairs than helicoils, timeserts are better, I,m sure I can fix it, would be cheaper than the alternative

We normally prefer time-serts. Go with this^ Also helicoil will work just fine.

Blowing spark plugs out of heads was a time honored ford lightning tradition. MANY of the plug holes have been rethreaded using a product called "time certs." Yes, the repairs were done with the heads still on the motor.

Look into it.

I agree 100%, a timesert is like a internally threaded bushing, where a helicoil is a coil of stainless, kinda like a slinkie, if its done properely they both work well, I have some AFR heads for a small block and they are like $3500 and every cylinder is helicoiled from the factory, in fact all holes even the ones on the end of the heads are helicoiled

I'd Helicoil it.
We've done a bunch and never had any issues, usually can turn it around in a day or so.
